The tumbler control key operating mechanism of this cylinder 13 carries the operating finger on the inner or rear end within the lock casing 10 as clearly shown in Figs. 3, 5 and 6'. This operating member 15 is adapt ed to engage in the recess 16 formed in the loweredge of the movable contact member 17 and operates the contact member to control a plurality of circuits in a predetern'iined manner. This movable contact member is slidably supported on suitable guides 18 formed in the lock casing and on its upper edge toward the left corner as shown in Fig.

. 3,1s' formed with a projection 19 adapted to engage one of the lugs as shown in Fi 3 to limit the movement of the contact memoer 17 inonedirection, while the lateral extension 20, on the latch member 21 engages the oppositeside of the lug 19 in the position of the parts as shown in Fig. 3, to prevent the movement of the contact member 17. This latch member 21- is pivotally mounted on the boss 22 between the movable contact member and the 'front wall of the lock casing as clearly shown in Fig. 6 andhasa curved lower edge asindicated at .23 adapted to lie in the path of movement of the operating member 15 for cooperation with said operating member and movement thereby. y I

A projection is formed at 24 on the upper edge-of the latch member 21 extending laterally overthe upper edge of the movable contactrmember 17 and adapted to limit the upward movement of the contact member during its sliding movement. A spring 25 has one end thereof engaged with the projection 20 of the latch member and the opposite end seated in the recess formed by the flange 26 in the upper right hand corner of the lock casing 10 as shown in Fig. 3, and which is adapted to normally more the latch member to its lower position as shown in Fig. 3, for locking the movable contact member 17 at either limit of its movement, at which time the lateral projection 20 is positioned adjacent either side of the projection 19 on the movable contact member 17.

The movable contact member 17 is provided wit-h a plurality of contacts indicated at 27,

28, 29, 30 and 31 respectively which are slidably mounted in bores 32 extending laterally in the body of the member 17 and normally projected by coiled springs 33 within said bores. Longitudinal passages 34 are formed in the movable contact member to receive bar members 35 which are adapted to close the circuit between contacts 27 and 28 respectively and contacts 29, 30 and 31 respectively, as shown diagrammatically in Fig. 9.

The contact 27 is adapted to engage with the stationary contact 36 mounted in the cover plate 37 for the locking casing which is preferably formed of insulating material. This contact member is in the position as shown in Fig. 3, at which time the movable contact 28 will engage with the stationary contact 38 for closing the respective circuits controlled thereby. The contact 29 is adapted to'engage with the stationary contact 39 when the movable contact member is at its opposite limit of movement from that shown in Fig. 3, while in the position shown in Fig. 3, the contacts 30 and 31 will engage with the stationary contacts 40' and '41 and close the circuits controlled there by. In this position as shown in Fig. '3,'the contac t 29 will not engage any of the stationary contacts on the insulating cover plate 37 and will not make circuit with the contact 39.

At the opposite limitof'm'ovement of 'the movable contact member 1 17, the contacts 27 and 28 respectively wilrbe mov'ed r elative to the stationarycontacts36 and 38 s"o that the contact 28 willengage contact 36 and the circuit between the two stationary contacts 36 and 38 will bebroken and noothercircuit made thereby. Irithisposition of the movable contact member,f contactsj31and 29 will engage contacts 39 and f0 respective ly and through their linlrable connection as shown in Fig. 9 will close, the'pircuit between these two stationary contacts for a purpose which will presently appear.

The cover plate 1, 37 is removablysecured to the lock casing 10 through suitable'screws 42, screw threaded in openings in thefront walls of the lock casing, while the forward portion of the lock casing is formed with an opening at 43 to provide an electriccable passage into the casing. p

The forward face of the lockcasing 10 is formed with a forwardly extending flange 44 forming a support for the insulating face 4-5 on one end of whichis secured the brackcts 46 carrying the relay solen0id 17Q A bra ckct 48 has a spring strip 49 secured thereto and which is positioned at the opposite end of the base and provided with an armature 50 adjacent the ends of the relay solenoid 47 for operation upon energization of said solenoid.

An armored gong or hell 51 adapted for electrical operation is mounted within a suitable armored casing 52 of any desired character to conceal and house thebell which is adapted for mounting in a convenient location on an automobile so that it will not be readily accessible and to which the cable 9 from the armored casing 3 is connected.

The casing 3 is suitably installed on-. an automobile convenient to the drivers seat so that the key may be inserted in the tumb er controlled cylinder l f to permit the operation of the movable contact member 17, and

the armored cables 9 as shown in 1, are connected to the casing of the usual ignition andlight. controlling switch. 1 and to the armored casing 5. 2. mounting the bell 51. 5.3. in Fig. 8;, represents the battery as used in the automobile,- which is usually provided with a ground on the frame as indicated at 54 at one terminal, while the. opposit terminal is connected by'a Wire5 t th terminal 56 on the ignition and lightcontroh ling switch-1.

Througi the operation of the contact in this-switch 1, indicated diagrannnatieally at 57, the circuit with the battery from thewii'e is closed to the terminal 58 which supplies current to the wire 59 extending thru one of the armored cables 9 to the stationary contact 40 on the cover plate 37, and when the contact points 31 and 29 engage with the stationary contacts 39 and 40, the circuit will be closed to the wire 60 extending to the terminal 61 on switch 1 and through the wire 62 to the usual ignition system and apparatus of the automobile, so that it may be energized for the usual operation of said automobile.

In the position of the movable contact member as shown in Fig. 3, the circuit will be made between the stationary contacts 40 and 41 to the wire 63 and the bell 51, which is grounded as indicated at 64 to the frame of the automobile to provide a return circuit to the battery 53 so that upon the operation of the ignition switch as indicated at 57 in the switch mechanism 1 for the unauthorized use of the automobile it will be seen that the circuit to the alarm bell 51 is immediately closed.

A branch lead 65 extends from stationary contact 41 to the bracket 48 to which one end of the relay coil 4.7 is electrically connected. The opposite end of this relay coil is connected through the wire 66 to the stationary contact 36 and in the position of the movable contact member shown in Fig. 3, the circuit is closed to the stationary contact 38 which is grounded in any suitable manner on the frame to provide a return circuit to the battery 53 as indicated at 67.

The closure of the ignition switch as indicated at 57 will then close this branch circuit through the relay 47 which will energize the relay and draw the armature against the ends thereof and close circuits to the brackets 46 which is electrically connected by the wire 68 to the terminal 56 of the switch mechanism 1 providing a separate circuit with the battery 53 for maintaining the relay solenoid 47 energized even though the switch 57 is moved to open position.

YVith the parts in the position shown in Fig. 3, it will be seen that the operation of the switch 57 will energize the alarm bell 51 and produce the operation of the same, at the same time energizing relay solenoid 47 which will of its own operation close an independent circuit therethrongh with the battery. 53 by h engag m n t th a matin'e 0 wit th end of. the relay solenoid. and thereby maintain the circuit to the alarm hell 5 1 until t ra l e ntaet membe 7 n eparated through the use of the key and the cylin, der mechanism l3te operate the leuer: 1,5 and open the circuit.-

The .operatton .of themovabie contact men ber rom he nesitienshown inFis- 3 to its pp i limi a m eme t-will b eak the sh re ment ened citaiit a dnake s r w between ta ionary 3.9 aud s -h t the anthorizedorsrannnetthenew mobile by. the eiosure,o-f .-the system t g e ng wi e me hanism! by ating contact 57 will permit theusgalopgggr tion of the automobile without closing the circuit through the alarm system or the relay solenoid 47.

From the above description, it should thus be clear that an efiicientelectrical alarm system and ignition control has been provided for application to motor vehicles encased by suitable armor, to prevent unauthorized persons from readily operating the automobile through closure of the ignition system or access to the parts without considerable difliculty to stop the alarm which operates automatically after initial energization.
